APPARATUS AND METHOD FOR PROVIDING EMERGENCY SERVICE IN A BROADBAND MOBILE COMMUNICATION SYSTEM

摘要

The present description relates to a method for providing an emergency service for a terminal in a broadband mobile communication system, wherein the method involves receiving an emergency service message for the terminal in an idle mode having a paging cycle consisting of a paging available interval and a paging unavailable interval, and comprises the following processes: receiving a control message including information which indicates that the emergency service message was transmitted in the paging available interval, and information which indicates the point in time the emergency service message was transmitted; if it is verified, from the received control message, that the point in time the emergency service message was transmitted is after the paging available interval, maintaining the idle mode until the emergency service message is received; receiving a first message including a system parameter in the paging unavailable interval, and comparing whether the point in time the first message was received and the point in time the emergency service message was transmitted correspond with each other; and, if the points in time correspond with each other, shifting to a wakeup state from the point in time the first message was received, and receiving the emergency service message.
